(2x-1) . (3x^3 + 375) = 0

`(2x-1)*(3x^3+375)=0`

`⇒`$\left[\begin{matrix} 2x-1=0\\ 3x^3+375=0\end{matrix}\right.$

`=>`$\left[\begin{matrix} 2x=1\\ 3x^3=-375\end{matrix}\right.$

`=>`$\left[\begin{matrix} x=\dfrac{1}{2}\\ x^3=-125\end{matrix}\right.$

`=>`$\left[\begin{matrix} x=\dfrac{1}{2}\\ x=-5\end{matrix}\right.$

Vậy `x=1/2` hoặc `x=-5`
